Article

Summary

The cyclic olefins cyclopentene, norbornene, exo- and endodicyclopentadiene, exo, exo-norbornadiene dimer, and indene were homopolymerized by Mo (CO)5py/C2H5AlCl2/(C4H9)4NCl. In most cases, the polymers obtained were of the ring-opened type, but also showed ringretention to varying degrees, depending on the temperature of polymerization. Generally, ring-opening polymerization was favored at lower temperatures. The dicyclopentadiene monomers gave crosslinked materials, showing reaction through both double bonds.
